Knowledge Sharing and Capacity Building

The Regional Knowledge Center for Marine Plastic Debris (RKC-MPD) is a specialized branch created within Economic Research Institute for ASEAN and East Asia (ERIA) to combat marine plastic pollution in ASEAN+3 region by serving its member states. RKC-MPD facilitates networking among stakeholders, raises awareness, promotes innovative actions in each county, and facilitates national and regional cooperation to solve the marine plastic debris problem.

Ocean Under Stress: In 2050 Around 90% of Coral Reef Would Die

by Devina Anglingdarma • 22 September 2021

Scientists have predicted that by 2050, with the way climate change is unfolding, more than 90 per cent of coral reefs around the globe will be at risk or disappear.  



National Framework to Tackle Marine Plastic Debris

Solving the issue of marine litter requires the involvement and cooperation of ministries in charge of fishery, coastal and river management, land-based waste management, industries producing and using plastics, recycling industries, and others.

Government Initiatives

To prevent marine plastic litter, various policies, such as reducing the use of single-use plastics, preventing littering, expanding waste collection services, and recycling, have been applied in this region.

Scientific Knowledge

There is still a lack of reliable data and short of scientific knowledge on marine plastic debris. Although we should take some actions, based on the precautionary principle, we also need to enrich scientific knowledge in various fields.



  • Environmental and Sustainability Challenges in the Mekong Subregion

    by Venkatachalam Anbumozhi, Michikazu Kojima, Ellen Putri Edita, Hendro Putra Johannes, and Dian Lutfiana | November 2020

    The Mekong Subregion – Cambodia, the Lao People’s Democratic Republic (Lao PDR), Myanmar, Thailand, and Viet Nam – is not only host to the fastest growing economies in the Association of Southeast Asian Nations (ASEAN), but is also rich in natural resources and biodiversity and has a culturally diverse urban population. Returns from the continued economic growth have raised incomes and improved people’s well-being, but have also resulted in many environmental challenges.

  • Applying the extended producer responsibility towards plastic waste in Asian developing countries for reducing marine plastic debris

    by Hendro Putra Johannes, Michikazu Kojima, Fusanori Iwasaki, Ellen Putri Edita | April 2021

    Applying EPR system for plastic waste in developing countries faces many challenges, such as the existence of a market-based collection system of recyclables, high transportation cost, lack of waste collection services in rural areas, a limited number of facilities to manage certain types of plastic waste, insufficient pollution control and free riding and orphan products. The challenges, furthermore, can be minimised by differentiating the responsibility of producers, focusing on rural and remote areas, involving informal sectors, creating joint facilities in recycling parks, expanding waste management collection services, increasing the use of EPR and minimising free riding.

  • Regional Waste Management – Inter-municipal Cooperation and Public and Private Partnership

    by Michikazu Kojima (editor) | October 2020

    To reduce the risk of COVID-19 and the leakage of plastic waste to the ocean, waste collection and disposal services should be expanded middle and small cities, and rural area. This report shows economies of scale in waste management, reviews regional waste management in Japan, the Philippines, Thailand, and Viet Nam, and identifies some types of regional waste management schemes, including regional waste management with Public Private Partnership.

  • Strengthening Waste Management Policies to Mitigate the COVID-19 Pandemic

    by Michikazu Kojima, Fusanori Iwasaki, Hendro Putra Johannes, Ellen Putri Edita | July 2020

    The coronavirus (COVID-19) pandemic has raised issues with waste management. In ASEAN countries, the increasing amount of medical waste during the pandemic is not in line with the availability of waste management facilities. Furthermore, the amount of plastic waste is also rising because people rely more on food delivery services. In this difficult situation, it is crucial for ASEAN countries to strengthen their waste management policies.

  • Plastic Recycling: Policies and Good Practices in Asia

    by Michikazu Kojima | March 2019

    The need for a circular economy for plastics has become a global concern. Plastic marine litter has been recognised as a global environmental issue, and many countries have introduced policies to reduce single-use plastics. Recycling of plastic waste should also be strengthened to reduce plastic marine litter. This report aims to provide basic information and policies on plastic recycling, including good practices in Asian countries.

  • Sustainable Marine Development

    by Fauziah Zen, Heru Santoso, Maxensius Sambodo, Michikazu Kojima | September 2019

    Indonesia has the largest economic exclusive zone in Asia, and Japan the second largest. Marine resources are their main development assets. Indonesia and Japan rely on marine logistics and fisheries, of which infrastructure and connectivity are important aspects. Both countries are prone to disasters, including tsunamis, and should improve their disaster management. And both countries should improve their waste management to eliminate marine debris and pollution.
